RWBY: The Unknown Sibling
(Harry is two years older than Ruby and one year older than Yang)

Ruby Rose looked at the pictures of her Fathers team. She immediately noticed a set of similarities between Herself and Qrow Branwen, her uncle.

"Hey Rubes, How's it Yanging?" Ruby looked up and saw her elder half-sister join her in the living room.

"Yang look at this picture." Yang took the image and her eyes widened.

"That's your Mom in the white cloak, Dad by the tree, Uncle Qrow god he looks young and that's my Mom." Ruby shook her head and swiftly got changed into form fitting workout gear.

"Take a proper look at me and then the picture." Yang looked again and her eyes widened. Ruby had nothing in common with her or Taiyang!

"Rubes you do know that children can strongly take after one parent or another...so what your thinking is highly unlikely." Yang said contemplating her response.

Taiyang Xiao Long bounced into the room. Losing two women from his life had really hurt him, even though he knew his youngest was not his by blood, thankfully she looked so much like her mother that no-one asked many questions.

(Private Drive, Surrey)

Harry, cracked open a can of lager. Was he underage to drink, yes. But he did not give a crap, he had just seen his Godfather for and no-one had kept in contact to keep him from doing anything stupid.

His Uncle had noticed something was up and promptly demanded what was wrong. "Drink this. It's not good for you in the long run but for now it helps numb the pain."

Now here he was sitting in the park with three four packs of lager. The alcohol was working as he didn't notice the woman in white walk up to him.

Summer Potter gasped. It had taken her sixteen years but she had found him. She had found her son. Summer knew of the Wizarding World as her younger brother James was a powerful wizard and unfortunately she hadn't developed as powerful enough core.

Instead of being cast out of the family, her parents had sent her Remnant. Remnant was a continent that eventually drew all squibs to it and it allowed them to harness different skills such as aura.

Summer had been adopted by a pair of distant cousins, who had taken on the name Rose. Summer remained in contact with her parents and found out that James had been sterile, in order to protect her birth parents Summer had given her brother, her first born Haridian 'Harry' Branwen.

She had promised to come and visit but when she re-entered Remnant via a Portal she had required giving up something of importance.

However, she became pregnant with Ruby on a two-person mission with Qrow, then they split up and she became intimate with Taiyang shortly after.

She had spent sixteen years traipsing the world, trying to remember what she had surrendered to pass through for the fourth time.

1st- Knowledge of the rift and coming and going voluntarily
2nd- Giving up her son
3rd- Three months off her life
4th- Would be a blood tribute.

Summer gathered her courage, lowered her hood and strode towards her son. Harry looked up and saw someone moving all to swiftly towards him and he went for his wand as did a concealed Remus Lupin.

"A little young to be drinking this morning."

Harry snorted sounding a lot like Qrow "And you care because?"

Summer stumbled backwards slightly "What would your parents think of your attitude?"

Harry shrugged "They died...I love with my Aunt and Uncle." Remus's eyes widened, his nose never lied to him so far and it was telling him that this woman was James's sister.

"Where in the name of Merlin have you been Summer Potter!" He snarled pulling off his invisibility cloak.

Summer stated and pulled her scimitars, Harry scrambled backwards and pulled his wand. Magic pulsing and his aura fluctuating behind it's barriers "Where have you been? I thought Dumbledore had listened to my requests Professor of NO-FUCKING-MINDERS!"

"You need to calm down. I came to watch you because you look a right mess. What would Sirius want you to do?" Remus turned to the cloaked woman "Why are you here Summer? Shouldn't you have been here for Harry oh I don't know SIXTEEN years ago."

Summer waited "Finished? For that manner, getting from where I lived here requires tributes. One such tribute can be knowledge/memories/clothing/blood etc. I've paid the tribute three times and I will pay it again and so will Harry hopefully."

"What do you mean hopefully? I don't know you."

Summer let a year fall "You should have been notified when you turned eight."

Harry's eyes narrowed "About what?"

"The truth. Who you really are and why I wasn't around."

Summer and Remus had taken sharp gasping breaths to ease her heart rate as Harry's magic began crackle ominously around him "I received nothing. Tell me everything and no lies."

Summer and Remus looked at each other and nodded "Will you be the binder Remus?" the Werewolf nodded.

Remus placed his wand on top of Summer's trembling hand and instructed Harry to place his hand on top. The process was repeated and Remus began. "Do you Harry James Potter, swear to listen entirely to what Summer Rose will say?"

Harry nodded and repeated the statement "I, Harry James Potter, do swear to listen entirely to what Summer Rose will say." The binding carried on basically ensuring Harry would not lash out in anger, rashly or unfairly on Summer if the information destroyed everything he knew.

"You are related to the Potter family. Not through my little magical brother James but through me...You were born in the equivalent of July 31st in Vale Hospital in Remnant. I brought you here because you displaying incredibly powerful magic and aura bursts whilst still in my womb. Magic and Aura do not normally mix and a child of both is either a squib or a wizard. It is as it sounds. Most squibs find their way to Remnant and never return because the price is often either too much or too precious. I have made the trip three times. Once to lose contact with my family and to never contact them again under my own power. The second was when I had to give you up, the hardest thing I ever had to do but in a letter it was conditional. You were to remain with James and his wife to gain control over your magic and over the Summer holidays you would stay with me and your father to control your aura. Once you had taken your OWLs you were to be offered a choice stay here and be tutored in aura or go to Remnant and learn to control your aura and your magic would be optional...the Third time was recently, I thought James had forgotten the deal so I sacrificed three months to come back and find you. I ended up in Japan and since the other occasions stack..."

Harry nodded and hugged Summer tightly "I can't call you mum as I have only just met you but I'll take that offer. Let me grab a bag, owl and we can go to Gringotts for clarification."

In their conversation they failed to hear a faint pop "Step away from Harry." A strong powerful voice called. Harry turned and his eyes took on a steely glint making Summer grin 'He is his father's son but with one eye of each'. "Albus Dumbledore, long time no see." She called out.

Albus Percival Wulfric Brian Dumbledore was many things and one of said things was the inability to forget voices as faces "Summer Alicia Potter? My you have grown into a beautiful young woman. Can I ask why you've come back?"

"To get my son. Or a he prefers it his Aunt. As for you, I need some answers and I'd prefer it if you came thoroughly clean and I don't have to get my White Roses dirty, they are such a pain to clean." Summer stated her hands plainly drifting towards her scimitars.

Dumbledore nodded "I have such a letter and deemed Harry unready to learn such a thing. It was for his own good." Harry's fraying temper snapper and for a slight instant his green eyes flickered to a complete heterochromia of silver and red eyes with a complete central heterochromia of the pupil with the silver eye having a red pupil and the red eye a silver pupil.

"YOU...DID...WHAT!" Snarled Harry as his magic flared once again only to find the symbols of what looked like gates appear around him, Summer noticed that the Headmaster began to glow slightly as Harry focused more magic.

"He blocked your magic..." Summer gasped, Harry snarled as he charged the old man and Dumbledore's eyes widened as Harry disappeared.

"Why? I want the truth."

"Or what?"

"You burn...The sorting hat said I would have done well in Slytherin. Tell me the truth and the Wizarding world doesn't burn."

Dumbledore felt hope rise in chest and with that he began to explain everything. Harry was connected to Voldemort by his scar; Said Dark Lord has created Horcruxes to stave off death and he did not talk to Harry at all last year because he was afraid of the potential connection. What Dumbledore didn't reveal was that he expected Harry to die and he himself would finish of Voldemort.

However, this small unspoken sentence was detected by Summer, whose semblance was manipulation of the wind enabled her to pick up minor thoughts based on miniscule twitches in an otherwise controlled face. "You're missing something…You want to be remembered as someone who has defeated two dark lords, you're scared of my nephew for potentially outshining you."

Dumbledore couldn't hide his shock and neither could Harry or Professor Lupin, Summer seized the initiative "Harry, hold on." With that Summer, summoned a hurricane and launched the duo sky high and towards London. Harry felt like he was on cloud nine "THIS IS AMAZING!"

Summer grinned "I was the flying enthusiast the only thing I could do magically without the assistance. I was the one who taught James…He was nowhere near as good as me. Brace yourself. This can be bumpy."

Summer and Harry landed in an alleyway, ten minutes away from the Leaky Cauldron. The impact caused a small crater but it didn't perturb the duo, Harry swiftly led Summer out to the Leaky Cauldron. Summer was surprised at how much things had remained the same than muggle London, she was more familiar with Manchester but she tagged along to get help her brother get his school stuff.

Harry opened the door to the Leaky Cauldron and immediately began pulsing his magic in an aura of 'Do not even talk to me. You immediately disbelieved me so why should I listen or care'. Everyone parted for him and the duo entered Diagon Alley. "What was that all about?"

"They didn't believe me about what I was saying and believed the corrupt government. I'm only here to clean out my vaults and flip the world the bird and leave. Tom Riddle is their problem and not mine."

"And if they bring you back?"

Harry smirked "Best come with body bags as I'm not taking prisoners." With that the pair ascended the steps to Gringotts Bank, Harry got in the line and waited until a Goblin came free.

"How can I help you?" Asked a bored Griphook.

"Greetings Griphook, may your gold always flow and may good profit always find you." Harry replied, silently kicking himself for not learning Gobbledegook.

Griphook looked at the people in front of him "How can Gringotts be of assistance Mr. Potter?"

"I need to check my holdings and do an inheritance test and get a genealogy test as well."

Griphook led them into a large open room and returned momentarily later with a pensive sized obsidian bowl and a jade knife "Mr. Potter, Mrs. Rose, the pair of you are to slice your palms and pour blood into the bowl which will then reveal the blood link if there is one and your ancestry."

Harry was livid "Get them off. Get everything off…" Griphook stared in shock. "It costs ten thousand galleons to do a full body purge…the pain is supposedly insurmountable."

"I've had the Cruciatus curse cast on me by Voldemort himself…Do it. Take the ten thousand galleons…" He fished inside his trousers and found eight galleons and enough sickles and knuts to make another three. "…An additional eleven galleons with a bit more if this thing can be done today and now."

Griphook nodded and took the money "Your will be done my lord."

Harry found himself in the bowels of Gringotts strapped to a hospital bed "Please don't make the suit green, animated or that I turn into Green Rage Monster."

The goblins chuckled "I'm Ajax, well when I started this I was filled with enthusiasm. Now it's gone, I'm going to inject you with several potions to purge your body. Unfortunately, it's going to hurt a lot."

Harry grinned "We'll see about that…"

Ajax grinned "A sense of humour? That'll leave later, I'm stabbing you NOW." Harry stiffened the potions were now in his blood stream.

"I'm going to leave you with my colleague Blackfire."

Harry groaned "C'mon you're leaving me alone with less angry Rosie O'Donnell."

The goblins including Blackfire who were restraining their laughter were letting it go now. They loved the character Deadpool "What do you want when you wake up?"

Harry groaned "Chimichangas…" He blacked out the moment the drugs began circulating; the entire exchange took about 40seconds.

Harry emerged from the Hospital a lot had changed. He no longer needed glasses, he was still thin but not skeletal bony thin. He was thin more like whip-chord muscle thin and he had an increase in height instead of coming in at 5'5, he had shot to 5'10 with possibility of hitting 6'0 when he had finished growing.

"Now what's the plan mum?"

Summer's eyes glistened with tears and she pulled him into a hug "Get some money both muggle and wizarding and we're doing some shopping and heading home…You have a sister and a cousin to see."

Harry grinned and the pair headed into Diagon Alley. The shopping trip was a blur and soon enough Harry was clad in jeans, baggy hoody and knee high black Kevlar military boots and Black elbow length fingerless gloves. He had also picked several musical records and soon enough he and Summer were out of the UK heading towards Japan "Why are we heading to Japan?"

"Portal back to Remnant and it coincidentally happens to be closest to where I live."

Harry nodded before falling asleep.

(Grimmauld Place)

Dumbledore stormed in, magic rolling off him. "How dare that boy abandon his destiny…He was supposed to die a martyr…Calm down we can play this into our hands. Now that Voldemort has appeared and Harry has disappeared we can start a smear campaign that he turned down my teaching…"

"Albus? Oh dear me, you look like you need a good cup of tea." Albus nodded and allowed himself to be looked after by Molly Weasley. She wasn't a considerably powerful witch but what she knew was charms and how to be creative with them oh and she could make a meal.

"Molly could you assemble the Order."

It wasn't until that evening when the Order could assemble and with that Dumbledore began his smear campaign.

(Summer and Harry)

Summer shook Harry and the pair disembarked the plane, headed out of the airport and once no-one was looking summoned their luggage and vanished on a gust of wind heading towards the mountains and a rift heading back to Remnant and Vale.
